This patch adds support for the bq27000 battery to the bq27x00 driver. The bq27000 is similar to the bq27200 except that it uses the HDQ bus instead of I2C to communicate with the host system. The driver is implemented as a platform driver. The driver expects to be provided with a read callback function through its platform data. The read function is assumed to do the lowlevel HDQ handling and read out the value of a certain register.
